In parts dry, Latino rum (9)
I believe the answer is:
sectional
'in parts' is the definition.
(I've seen this before)
'dry latino rum' is the wordplay.
'dry' becomes 'sec' (similar in meaning).
'rum' indicates an anagram (rum can mean strange or unusual).
'latino' is an anagram of 'tional'.
'sec'+'tional'='SECTIONAL'
(Other definitions for sectional that I've seen before include "Relating to parts" , "Coastline (anag)" , "in certain parts" , "in various pieces" , "Limited to a particular community -- 5 (anag)" .)
